Know About Laser Welding Through This Post!!!

The process of joining two materials together by using heat is called welding. This process is mostly used in construction-related works. Heat is used to melt the materials causing them to fuse upon cooling. Welding is required when continuous structures cannot be formed. It can be used to join similar as well as dissimilar metals. For dissimilar metals, a filler metal is used to help in the fusion. 

Types of welding

There are many types of welding depending upon the type of welds and techniques. Some important types are:

  • Arc welding (shield arc welding, tungsten arc welding, flux cord arc welding, etc.) 
  • Electron beam welding
  • Laser welding 

Out of all types of welding, the most common and preferred type of welding is laser welding. 

Laser welding:

Laser beam welding is a welding process in which two metals or thermoplastics are joined by using a laser beam. The laser beam is a monochromatic light and when it hits the surface of the material, heat is created. This heat causes the material on both sides of the joint to melt and fuse forming a weld. Types of laser welding depend on the amount of laser energy. 

Although laser welding is the most accurate process, it is not suitable for all types of metals. It is commonly used for metals like,

  • Aluminum
  • Carbon steel 
  • Stainless steel 
  • Nickel 

Laser welding was first invented by Marshall Jones in the mid-70s. Later in 1985, it was used by Toyota in Japan and has been in use ever since. 


  • Laser welding is a great process for producing deep and narrow welds. 
  • It is a high-speed process 
  • non-contact and single-sided process
  • Suitable for a range of materials with varying thicknesses.
